There are Rupay select credit cards which offer  OTT benifits like BOB TAIRA CC
your point is true i.e 95% of Rupay S C cards dont get OTT but not 100%
even for time being suppose considering your statement is true , My point is they advertised that we will receive the OTT benifits , otherwise they will be in Trouble for Mis selling and Mis leading
Most of us in this Groups have enough evidence for the same , you can check my above trailing msg with the link of Gdrive they advertised
